Safe motion monitoring using the small control systems PNOZmulti 2

Safe monitoring of your drives

The safe motion monitoring modules for the configurable control systems PNOZmulti 2 ensure safe monitoring of your drives. The extension modules, together with a base unit PNOZ m B0 or PNOZ m B1, monitor one or two axes. The safe motion monitoring modules for PNOZmulti 2 are easily configured using the software tool PNOZmulti Configurator. The tool can also be used to configure an independent module program (mIQ), which is then executed directly on the Motion Monitoring module. This brings significant benefits to you as the user: fine-granular configuration of several monitoring areas - such as velocity or rotational speed - is possible, which are then locally executed on the expansion module. That means greater flexibility for you as the user. Convenient diagnostic facilities and a wide variety of fieldbus and communication options are also provided.

All standard incremental encoders can be connected using drive-specific connection cables via an industrial interface, characterised by particularly high durability.

Safe monitoring functions with PNOZmulti 2

SS1 – Safe stop 1

With the "safe stop 1" function, the drive is brought to a controlled stop, after which the power supply to the motor is safely interrupted. Once at a standstill, the drive cannot generate any hazardous movements.

SS2 - Safe stop 2

With the "safe stop 2" function, the drive is brought to a controlled stop and then the "safe operating stop" is initiated. In a "safe operating stop", the drive's control functions are maintained in full

SSR - Safe speed range

The maximum speed must not exceed a certain value, and the minimum speed must not drop below a certain value. If either of these limits is violated, the drive is shut down.

A drive can only move in one (defined) direction. If the specified direction is violated, the drive is shut down safely.

SOS - Safe operating stop

The SOS - Safe operating stop - monitors the stop position reached by the axis and prevents any deviation from the position window. The drive's control functions are maintained in full. If the position strays outside of the monitored window, the drive is shut down safely.

With various blocks in the software tool PNOZmulti Configurator, the safety functions can be quickly and easily implemented
